Windows Server 2008 high internet usage

Hi all,

We have a Win Server 2008 which is using 5gb of internet per day, I have uninstalled symantec & vprotray.exe which what I thought was using it, to no avail, can anyone point in the right direction of where to look next please?
Thanks

Why does your server have internet access?
Rule no 1 in corporate networks is "block all external access".
Rule 2 is "allow some exceptions for AV updates and a mail gateway".
Anything else is asking for trouble.
